1. A method of obtaining an ultrasound image of a region of interest of a body under observation, comprising:
moving an all-optical ultrasound transducer with two degrees of freedom in a two-dimensional matrix array;
receiving, from the all-optical ultrasound transducer, at least three non-coplanar A-line signals,
wherein the received at least three non-coplanar A-line signals start from different positions associated with the region of interest;
generating three-dimensional ultrasound image data based on the received at least three non-coplanar A-line signals;
identifying a surface of the region of interest based on the generated three-dimensional ultrasound image data; and
generating a General B-mode surface (GB surface) image based on the received at least three non-coplanar A-line signals and at least one position of the surface of the region of interest.
